Patent CA-2101193-A1 (CA)
Inventor: WANG SANUEL S
IPC: C07C331/32
Filed: 1993-07-23
Abstract: Alkoxy and aryloxy isothiocyanates are produced by the reaction of a haloformate and an alkali or alkaline earth metal thiocyanate in the presence of water and (i) a catalyst comprising a six membered mononuclear or ten membered fused polynuclear aromatic, heterocyclic compound having 1 or 2 nitrogen atoms as the only hetero atoms in the ring and (ii) a co-catalyst comprising an alkali metal or alkaline earth metal salt of an acid having a pKa of about 10 -3 or below. The co-catalyst accelerates the reaction rate, increases product purity and reduces the adverse effects of impurities in certain grades of the thiocyanate reactants.
Patent CA-2103357-A1 (CA)
Title: Photographic processing apparatus
Inventor: GLOVER EDWARD C T S
IPC: G03D3/13
Filed: 1992-06-12
Abstract: In small processing machines, the rate at which material passes through the machine tends to be low due to its size. This results in the access time being long as it is the sum of the actual processing time at each stage, plus the crossover times between each stage, and finally the time it takes for the whole sheet of material being processed to emerge from the machine. Described herein is apparatus which allows the transport rate between each stage and the exiting speed of the material from the apparatus to be increased. The apparatus comprises a rotating drum (10) around which a guide (12) is arranged to define a processing tank (14).  Material to be processed is transported around the surface of the drum (10) in the processing tank (14) by transport roller set (26).  The roller set (26) comprises a fixed roller (28) to which rollers (30, 32) are pivotally connected. Roller (32) is lifted from against the surface of the drum (10) to allow the material to be switched out of the tank (14). Similarly, roller (30) may be lifted to allow the material to enter the tank (14) and lie against the surface of the drum (10).

Patent CA-2104897-A1 (CA)
Inventor: MOMONA MORIHISA
IPC: G06F15/177
Filed: 1993-08-26
Abstract: An object of the present invention is to provide an access system which can accommodate constant bit rate data irrespective of the traffic conditions and which also allows accommodation of variable bit rate data at a high circuit utilization efficiency.  The access system is constructed such that a master station first performs allocation of transmission right for constant bit rate data to all of slave stations for each transmission period for constant bit rate data.  The master station does not immediately perform allocation but reserves requests for transmission right for variable bit rate data, and after allocation of transmission right for constant bit rate data to all of the slave stations, the master station allocates the requests for transmission right for variable bit rate data to non-used regions within the transmission period.

IPC: B29C48/09
Filed: 1992-06-23
Abstract: A unitary, flexible, substantially noncollapsible catheter tube (30) of biocompatible material is comprised of hard and soft regions. The hard regions can be ring shaped or helical. The hard regions (20) provide sufficient rigidity to the tube to prevent collapse under normal usage as the interior and exterior pressures vary.

Abstract: An  implantable  atrial  defibrillator  and  method provides cardioverting electrical energy to the atria of a human  heart  in  need  of  cardioversion.    The  atrial defibrillator includes a first detector for detecting R waves of the heart, a second detector for detecting T waves of the heart, and a third detector for detecting atrial activity of the heart.  An atrial fibrillation detector is responsive to the third detector for determining when the atria of the heart are  in need of cardioversion.   A cardioverting stage applies the cardioverting electrical energy to the atria of the heart when the atria of the heart are  in need of cardioversion,  after the  second detector detects a T wave, and in timed relation to an R wave detected by the first detector after the detected T wave is completed.   The atrial defibrillator includes a timer for timing a predetermined delay time after the T wave is detected, which delay time must be completed before the atria are cardioverted in timed relation to a detected R wave to assure that the detected T wave is completed.

Patent CA-2129511-A1 (CA)
Inventor: GUTIERREZ FRANKLIN
IPC: H04Q3/47
Filed: 1994-08-04
Abstract: An intelligent call processing system is arranged so that each originating switch is provided with a local database called a "global title translation (GTT)" database, which receives a query fully identifying the calling station, typically in terms of its 10 digit number (i.e., three digit [NPA] area code, three digit [NXX] exchange, and four digit line identification). The GTT database responds to the query by identifying the particular NCP in the telecommunications network that contains the appropriate record for completing the call. If the GTT database does not contain an entry, or an error condition exists, a further query is launched to a centralized database, called a "universal global translation (UGT)" database. The UGT database then retrieves information identifying the particular NCP in the telecommunications network that contains the appropriate record for completing the call, and provides this information to the originating switch. The same information may also be provided to and stored in the GTT database, so that the GTT database is "self provisioning".

Abstract: Inorganic oxides of substantially uniform particle size distribution are prepared by contacting aqueous solutions of an inorganic salt and an inorganic base across a porous membrane (14) wherein the membrane contains a plurality of pores which allows for precipitation of a substantially mono-dispersed size inorganic oxide particles on one side of the membrane and precipitation of a salt of the corresponding base on a second side of the membrane (Fig.  1). The particles so prepared can be coated with an organo-metallic polymer having attached thereto an organic functionality to which a variety of organic and/or biological molecules can be coupled. Particles so coupled may be used for in vitro or in vivo systems involving separations steps or the directed movement of coupled molecules to particular sites, including immunological assays, other biological assays, biochemical or enzymatic reactions, affinity chromatographic purification, cell sorting and diagnostic and therapeutic uses. In a further embodiment, described herein are liposome compositions which comprise the substantially uniform size inorganic core coated with an amphipathic organic compound and further coated with a second amphipathic vesicle forming lipid (Fig. 2). Also disclosed are novel phenyl lipid compounds which serve as the vesicle forming lipid (Fig. 3). When the magnetic particles are electromagnetic wave-absorbing surface modified particles (Fig. 4), such particles provide for the preparation of liposome compositions which offer a method for the treatment of cancer, as well as infectious diseases.
